__________________________ is the sudden elimination of a species due to a catastrophic event.

• Mass Extinction

• Gene Flow

__________________________ is rapid evolutionary change followed by periods of stability.

• Punctuated Equilibrium

• Gradualism

• Adaptation

• Descent with Modification

Biological change over time that causes descendants to be different from their ancestors.

• Biogeography

• Evolution

• Speciation

• Gene Pool

Pinciple of natural selection that explains how beneficial traits should become more common over time, causing a change in allele frequencies.

• Adaptation

• Descent with Modification

• Variation

• Overproduction of Offspring

Body structures that are similar in structure but diffferent in function.

• Analogous Structures

• Vestigial Structures

• Homologous Structures

• Fossils

Study of embryological development in vertebrates that has led to support the theory of common ancestry among vertebrates.
